How to use it
A formula sheet is a revision aid, not a substitute for practice. Reading formulas builds recognition; applying them under time pressure builds recall, and it's recall the exam tests. The most effective way to use this sheet is alongside questions: attempt a question first, then check the sheet only when you're stuck, rather than working with it open in front of you.
Print it and keep it beside you while you work through TX questions. Once you stop reaching for it, you know the formulas are in place.
Test yourself on TX with 150 free practice questions, worked explanations for every answer, and a timed mock exam mode. Start TX practice →
